Hi guys, need some advice cuz I have no experience backpacking traveling....

Planning to go backpacking for a week at Bangkok next year with a friend of mine. Just wanna know what kind of budget am I looking at, what stuff (clothes, shoes etc) are necessary to pack and whether possible to backpacking with just carry on of under 7 kg (air Asia)?

Our planned budget is RM 1000 (excluding flight) each, but not sure if it's enough? We'll be very frugal but it'll be better knowing we overbudget instead of not enough money ><

Thanks!

if you backpack you can stay for more than 12 days with 1k budget
done that before this year 

Yup true that.
With such tight budget just try to avoid the famous night spots (if you know what I mean).
